Detailed Description

template<class SEQUENCE>
class vigra::SequenceAccessor< SEQUENCE >

Accessor for items that are STL compatible sequences.

It encapsulates access to the sequences' begin() and end() functions.

Usage:

#include <vigra/accessor.hxx>
Namespace: vigra

    typedef std::list<std::list<int> > ListOfLists;

    ListOfLists ll;
    ...

    typedef vigra::SequenceAccessor<ListOfLists::value_type> ListOfListsAccessor;
    ListOfListsAccessor a;
    for(ListOfLists::iterator li = ll.begin(); li != ll.end(); ++li)
    {
        for(ListOfListsAccessor::iterator i = a.begin(li); i != a.end(li); ++i)
        {
            *i = 10;
        }
    }
